ESDIS Weekly Metrics: March 23, 2023

EOSDIS Science Data Metrics

Note:

1. The volume distributed to end users per day, as a running average over the last 4 weeks, is 4.286 times the volume added to the archive per day.

LANCE Data Latency

Note:

1. Higher product latencies for:

   1. OMPS-Suomi NPP on 13, 15 and 17 Mar 2023, for unknown reasons.

   2. VIIRS-JPSS1 (Land) on 15 Mar 2023 and MODIS-TERRA and MODIS-AQUA on 16 Mar 2023, due to a delay in a data receipt causing a gap in L0 data, multiple products were delayed to avoid errors.

   3. VIIRS-Suomi NPP (Atmosphere) and VIIRS-JPSS-1 (Atmosphere) on 13 Mar 2023, due to delays from an ancillary file issue.

2. No LIS-ISS reported in the plot due to an error in our metrics system.

Note:

1. Latency for a data granule is defined as the time taken from the midpoint between the start and end of acquisition of the data for that granule to the granule’s being ready on-line for users to download.
2. Duration covered by the data for a granule is defined differently for different instruments (e.g., MODIS granules are 5 minutes long while OMI NRT granules are 13 to 136 minutes long).
3. Over the last four weeks, over 95% of NRT data requests for all instruments except for nine instruments (AIRS-AQUA, MODIS-AQUA, MODIS-TERRA, OMI-AURA, OMPS-Suomi NPP, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), VIIRS-JPSS-1 (Atmosphere), and VIIRS-Suomi NPP (Atmosphere)) were satisfied within 3 hours. For AIRS-AQUA, MODIS-AQUA, MODIS-TERRA, OMI-AURA, OMPS-Suomi NPP, VIIRS-JPSS-1 (Land), VIIRS-Suomi NPP (Land), VIIRS-JPSS-1 (Atmosphere), and VIIRS-Suomi NPP (Atmosphere) over 93%, 85%, 81%, 92%, 87%, 85%, 70%, 85%, and 85% of the NRT data requests were satisfied within 3 hours, respectively.
